Reaction Conditions

Reaction Steps

A solution of 4.98 g (0.033 mole) of phthalic anhydride and 5.42 g (0.037 mole) of TMPD in 40 mL of toluene was stirred and heated at 80° C. for approximately 30 hr. The solvent was evaporated and the crystalline residue washed with cold toluene and dried to give 5.95 g of 2,2,4-Trimethyl-1,3-pentanediol monophthalate. Crude 2,2,4-Trimethyl-1,3-pentanediol monophthalate (1.00 g) was recrystallized from 5 mL of toluene and washed to give 0.95 g of pure 1-(2,2,4-Trimethyl-1,3-pentanediol) monophthalate, m. p. (differential scanning calorimetry) 127.0° C.
